This invention relates to window fastening means and it involves meansfor guiding the window sash in the frame and for positively locking thewindow sash in any desired position in the frame, the guiding meansbeing so constructed that it provides a weather-strip.

The novelty of the invention will be described hereinafter, referencebeing had to the accompanying drawings in which:

Fig. 1 is a perspectiveview of a window frame and a pair of sashes towhich my invention is applied.

Fig. 2 is a view partly in perspective and partly in section of awindow. frame and a sash to which my invention is applied.

Fig. 3 is a perspective view of part ofthe sash-guide and weather stripvand Fig. 4 is a fragmentary perspective view of the sash.

The upper and lower sashes are both constructed substantially alike soit will be necessaryto describe in detail only one of them.

The window frame 1 consists of the usual sides, top and bottom exceptthat in each sash guide-groove is a combined weather strip and guideformed of. a single sheet of metal to provide side flanges 2 and 3 andan intermediate trough-shaped guide having flanges 1 and 5 at rightangles to the flanges 1930.

sashes. The cases have tubular extensions 20 which open at the inneredges of the rails through plates 21. In the tubular portions are boltsor detents 22 having collars 23 against each of which one end of a coilspring bears, the other end of the coil spring bears against theplate21. Outside the plate 21 is a cam actuating lever 25 pivoted to the boltor detent 22, the cam face 26 of the lever riding on plate 21 to causethe withdrawal of the end of the lever from the teeth of the pinion gearwhen the lever is in the dotted line position shown in Figure 2, thatis, when the lever is swung down to rest upon the stop 27 carried byplate 21.

When the lever 25 is in the position shown in dotted lines in Figure 2,the pinion will be free to'rotate. Then, the sash can be raised orlowered because the pinion will ride on the rack. Sash weights may beused if necessary but they will not always be required. When the sash isin the proper position, that is, either raised or lowered, the operatorcan swing the lever to the full line position shown in Figure 2 so thatthe bolt Will-engage between the teeth of the pinion and lock it againstturning. Then, the sash will be held against movement in eitherdirection. In other words, the window lock is thus pro- 2 and 3.Therefore, the guide has a central vided.

The window sash, for example, the one designated 8, is provided with anedge groove 9 having side flanges 10 and 11 which overlap the flanges &and 5 so thattheyride in grooves 12 and 13 formed by the flanges 4: and5 and the rabbet strips 14 in the frame.

What I claim and desire to secure by Let" ters-Patent is I Incombination, a window frame having a 'vertical rack, a sash having arecess therein,

a hollow metal housing in the recess'having a tubular portion extendingthrough one rail of the sash, a plate on the tubular portion secured tothe rail of the sash, a pinion in the housin meshing with the rack, aspringpressed b0 t in the tubular portion extending through the plate, acam-lever connected to the extended end of the bolt, the cam portion ofwhich bears against the plate to permit the bolt to be withdrawn out ofengagement 5 with the teeth of the pinion, the spring being eflI'ectiveto urge the bolt into engagement with the inion, and a stop membercarried by the p ate below the lever to limit the swinging movement ofthe lever.
